Asynchronous computer-based conferencing offers several unique capabilities as a medium. Participants can read and write messages at whatever time is convenient for them, groups can interact even though participants are geographically separated, and messages are available to readers almost instantly. Because the medium has served for over a decade…

Describes the use of the Brown scale and reports the results of its use in an experiment. Describes the instrument and details the experiment. Concludes that the Brown scale is a valid and reliable instrument for measuring attitude toward computer instruction. A copy of the instrument is included. (CW)

Proposed are the use of implementation strategies available to teachers through the application of Robert Gagne's nine instructional events. The application of computer technology in science education is discussed. (CW)

The Biological Sciences Curriculum Study (BSCS), with support from the National Science Foundation, is conducting a three-year project to develop a model for implementing educational computing in school science. This paper explains the tentative model in detail and presents the results of a pilot test of the model, which project staff conducted…

Previous studies have documented the effectiveness of feedback in improving students' achievement, but few studies have examined the effectiveness of summaries or reviews. This study examines the respective and combined effects of feedback and review on students' achievement, retention, and level of cognitive development. A total of 55 ninth-grade…

Described is the design and evaluation of a learning unit which includes the basics of computerized feedback control. Included are sample topics, descriptions of the achievement measures, and conclusions of the study. (CW)

Given are instructions for teaching spreadsheet use for problem solving in mathematics. Examples of relevant problems from algebra through calculus are provided. The advantages of using computer spreadsheets in this application are stressed. (CW)

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

The goal of the Educational Technology Center (ETC) Computer-based Conferencing Project has been to explore the potential of computer-mediated communication to support teachers in collegial exchange about their subject and practice, and to develop recommendations for future applications and management of such conferences. The purposes of this…

Properties of information most likely to attract student attention and how students use information they generate are clarified. Students' expectations of empirical information in geometry and the design of a new version of the Geometric Supposer are discussed. (CW)

Several models for preparing preservice and inservice teachers to use microcomputers in science teaching are described. A summary of research on the topic is included. A list of competencies needed by teachers to use microcomputers in teaching is provided. Recommendations for implementing computers in teacher education are suggested. (CW)

Describes the underlying pattern that, once seen, will allow students to describe the shape of any hydrogen orbital. Involves the exponential form of the orbitals. Provides computer-generated plots of this concept. (CW)

Described is a series of computer tutorials developed to teach students a logical method of problem solving for chemistry. The structure, pedagogy, and problem-solving strategies of the computer software program are described. (CW)

Presented is an illustration of the use of a computer spreadsheet program, Microsoft Excel version 1.5, for solving complicated chemical problems. Examples of spreadsheet output are provided. (CW)

Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)
